Anyone who has attended SF/F conventions has met the sexists in our midst. They are tolerated because they've always been a part of our genre. Many of them are the authors and fans we loved when we were younger, so their sexism is excused with a wink and a roll of the eyes like they're our beloved senile grandfather passing gas at the Thanksgiving dinner.

But that attitude merely prolongs the harm they do. So let me be blunt to the sexist farts of the SF genre: We're tired of your sexism and hate. Clean up or ship out. You're holding back the genre we love. And it's time for the men of SF to step up and also say this behavior is not acceptable.
